A Case of Syphilis Suspected Preoperatively as a Case of Tongue Cancer

Figure 1

Clinical findings of the patient. (a) A mass lesion of the tongue. An exophytic mass measuring 20 mm in diameter was observed on the right side of the tongue (arrowheads), which was surrounded by a flat white leukoplakia-like lesion (dotted line). (b) Magnetic resonance imaging with gadolinium contrast. Enhancement of the lesion (white arrowheads) at the right edge of the tongue is observed. The tumor measured approximately 4 mm in thickness. (c) Ultrasound examination. An enlarged lymph node was detected in the superior internal jugular node area. The node was round and showed internal heterogeneous echoes; therefore, it was suspected as a metastasis. (d) Computed tomography with contrast. An enlarged lymph node is seen on the right side of the neck, containing a low-density area within and an enhancing edge, similar to the characteristic findings of lymph node metastasis from squamous cell carcinomas.
